hdf file naming convention

mld.yyyyddd.hdf.gz

mld = mixed layer depth (units of m )
yyyy = year
ddd= day of year of the start of each 8day file
hdf = file type
gz = compressed with gzip (uncompress with gunzip)

The hdf files have metadata contained within them, which can be examined, for example, with program "ncdump".
